HAND TOOL Application filed November 13, 1926. v Serialrto', 148,148.

The present invention relates to new and useful improvements in toolsand it pertains more particularly to tools of the class known as handtools. 7

It is one of the primary objects of the present invention to provide atool which is 'highlyefiicient and, at the same time, may be constructedat relatively low cost.

It is a further object of the invent-ion to provide a hand tool in whichthe blade of the tool, while being securely'retained in a suitableholder while in operative position may be readily removed therefrom forthe urpose of sharpening, renewal or the like. lVith the foregoing andother objects in View, the invent-ion consists of a holder'provided witha suitable abutment with which 7 the blade is adapted to engage and anoperating handle, which operating handle constil tutes resilient meansfor retaining a blade in operative position with respect to the saidabutment and holder and, at the same time, permit of its ready removalfrom the holder i for various purposes Reterring to the drawings 1 IFigurefl is a View in elevation of a hand tool constructed in accordanceWithone form V of the invention; 7

In carrying out the present inventioman elongated strip of suitablematerial is employed. This elongated strip constitutes a blade holderand is provided at one end with a loop 5, the free end of whichis spacedwith respect to the body portion Got said holder, as shown inthedrawings. The t'ree end ot'the loop 5 is provided with a notch or thelike 7. The body portion 6 is provided with a groove 8 whichextendslongh tudinally thereof and this groove is adapted to receive theblade 9, whi'ch'in the present illustration isshownas asaw blade.

In'that form of the invention shown in Figures '1, 2 and. 4, the blade 9is cutout as at 60 to provide ashoulder in the form'of an angular wall61, a. straightwall 62 being pro:

vided opposite to the wall 61. Inthis form of the invention, theabutment designated 63 is formed inany desired manner, and it y lieswithin the cut-out portion of the blade and in engagement with theangular wall thereof. r

With the parts inthe position shownrin Figures 1 and 4, it will beapparent thatthe resiliency or" the loop 5 of the holder is exerted inthe direction of the body portion 6 of the holder as designated by theline A-'A Y and also in the direction of the abutment as designated bythe line 13 13, which resiliency tends to at all times maintain theblade in the loop is sprung sufiiciently to permit" of y the angularwall 61 Tengagingthe abutment, it being understood that the resiliencyof the loop permits of sufiicientmovement of the blade longitudinally ofthe holder to permit f of this operation. If now the loop be released,the bladelis forced inwardly of the slot 8 of the holder and forwardlyof the holder and engagement between the angular wall 61 and theabutment 63 is maintained byrthe resiliency ofthe loop 5.

The rear end of the blade 9 has an angular portion 16 which-is receivedin the notch 7 of the loop 5 for the purpose of preventing accidentaldisplacement of'the blade relative to the holder.

In the form of the invention shown in Figures 3, 5 and 6, the forwardend of the blade 9 is cut away to form a projecting member 11 whichprovides a'shoulder. or abutment' 12. r

In that form of the invention shown in Figure 3 the forward end ofthegroove 8 preferably terminates short of the end of the body portion 6 ofthe holder and is undercut to provide an abutment with which shoulder V12, provided by the member 11, is adapted to engage, as more clearlyshown in Figure 8. In the form of the invention shown 1n F1g-.

'ures 5 and6, an abutment 2.0 is provided by distorting the side wallsof the slot 8 in the body portion 6, as indicated at 21 in'Figure 6 andasshown-in Fig. 11. It will be understood that the action of placing andremoving the blade is the same in this form of the invention asheretofore described. V V

In that form of the invention shown in Figures 7' and 8, the bodyportion of the tool is formed with a recess 22, which construe:tion-provides an abutment 24 for engagement by the shoulder 26 formed onthe blade 9.

I shoulder 26 is preferably formed by cutting the back or rear edge ofthe blade 9 as indicated at 28 and forcing a portion of the -materialfrom which the blade is formed,

laterally outwardly with respect to the bodyportion thereof. In thisform of the invention,it*will be noted that the blade isretained inposition and removed from the holder in the same manner as in the formsheretofore described.

In that form of the invention shown in 7 Figures 9 and 10, it will benoted that a pin 30 is angularly positioned'in the slot 8 of the bodyportion 6 of the holder,which pin provides an abutment for the blade 9and in this form of the invention, the rear edge of the blade 9 isprovided with a notch or cut-out portion 32 within which the end of thepin 30 is received when the blade is placed in the holder, it beingunderstood that the placement of the blade inthe holder and the removalof the blade therefrom is the same as in blade thus lending rigidity tothe same during 1 to 3 inclusive and Figure 5, in which the bladeprojects beyond the holder as indicated by the reference character 40has its advantages in that it permits of the blade being used inrthemanner of a keyhole saw, for ope eration in relatively close quarterswherespace or dimension would not 'permitof the use of a tool of fullsize. I 7

From the foregoing, it will be apparent that the present inventionprovidesa new and improved form of hand tool in which the blade isrigidly held, or retained in the holder when in its operative'p ositionwith respect thereto and at the same time, the, blade is capable ofready removal from the holder is if when desired, and whileinlthepresent in-:

a groove extending therealong', an abutment c in said groove, a handle'for said holder, said handle being resilient, and spaced with respect tothe abutment, and a blade, said blade havmg a notch 1n its back edge,for engage ment with said abutmentl'to limit movement of said blade inthe direction of said abutment,and said blade having 'ineans for interengagement with the handle of the holder to prevent movement of theblade inafdirection away from the holder, j V I 2 A hand tool comprisingaho'lder having a groove extending therealong, an abutment in saidgroove atthe forward'end of the holder, a resilient handle formed-uponthe rear end of said holder, and ablade adapted to be received ,in thegroove ofthe holder, said blade being notched for the reception of theabutment in the groove, and adapted to be engaged by said handle wherebythe blade is secured in the groove of the holder between the abutmentand the handle Signed at New York, New York, this 9th v day of November,1926. r r JACOB G.
